Abstract (en)
[origin: WO8101966A1] The liquid spray device includes an oscillator for producing a fan spray with liquid droplets of uniform size. The oscillator is constituted by a power nozzle (15), a pair of side walls (20, 21) forming a pair of vortex spaces (30, 31) offset from the power nozzle, a pair of inwardly extending protuberances or deflectors (20B, 21B) downstream of which are a pair of inlets (181, 191) to passages (18, 19) leading to exits (16, 17) adjacent the power nozzle, and an outlet throat or aperture (24) having a pair of short wall surfaces (26L, 26R) defining an exit throat of any value selected from about 30` to about 160` so that the fan angle can be selected to be from about 30` to 160`. This structure results in an oscillator which has a relatively low threshold of pressure at which oscillations are initiated and, most importantly, the liquid is issued in a much more uniform fan pattern that heretofore possible. In a preferred embodiment the liquid is a windshield washer fluid and the oscillator is incorporated in a nozzle for an automobile windshield washer assembly for issuing a fan spray of washer fluid onto the windshield.
